@pasdedeuxproj @yaneerbaryam Air cleaner type filtration won't 'protect' you from anything. It's mitigation (in a given situation fewer people would become infected, or alternately, time to infection would increase), but there is no way to avoid breathing some contaminated air before it gets filtered.
@Pasdedeeuxproj@yaneerbaryam空气滤清器类型的过滤不会“保护”你免受任何伤害。这是一种缓解措施（在特定情况下，感染人数会减少，或者感染时间会延长），但在空气被过滤之前，无法避免呼吸一些受污染的空气。
